The fourth Yama to Sora and Circle U-Dash collaboration stars adult performer Aoi Kururugi as Fuyuka Kimijima, the exemplary student council president with a deeply submissive exhibitionist streak. After school she strips and masturbates by an empty classroom window, then exposes herself near adult classmates on their way home. When a stranger catches her outdoors and praises her naked body, the humiliation excites her enough to beg for his cock. Having discovered the thrill of being watched, she surrounds herself with men, embraces her masochistic desires, and performs a naked school strip while declaring that she will never hide her true self again.
